Hyperbolic Function Evaluation
\[\begin{aligned}
\sinh(x) &= \frac{e^x-e^{-x}}{2} \\
\cosh(x) &= \frac{e^x+e^{-x}}{2} \\
\tanh(x) &= \frac{e^x-e^{-x}}{e^x+e^{-x}}
\end{aligned}\]
Variables
sinh = hyperbolic sine value
cosh = hyperbolic cosine value
tanh = hyperbolic tangent value
x = independent variable
Description
What is this formula?
These formulas calculate the main hyperbolic functions using exponential expressions. Hyperbolic functions are analogous to trigonometric functions but are based on hyperbolas instead of circles.
When to use it
Use these formulas when solving differential equations, modeling catenary curves or analyzing hyperbolic relationships.
Example
For:
x=1
sinh=((℮^1)-(℮^(-1)))/2≈1.175
cosh=((℮^1)+(℮^(-1)))/2≈1.543
tanh=((℮^1)-(℮^(-1)))/((℮^1)+(℮^(-1)))≈0.762
